Description

M/A-COM’s MAAD-007077-000100 is a GaAs FET

4-Bit digital attenuator with integral driver. Step size

is 1 dB providing a 15 dB attenuation range. This

device is in an PQFN plastic surface mount pack-

age. The MAAD-007077-000100 is suited for single

supply applications where accuracy, fast speed, low

power consumption and low costs are required. For

dual supply designs without switching noise, use

MAADCC0006.

1. Pins 10 & 29 must be isolated.

2. Vee is produced internally and requires a .1 µF cap to GND.

Generated noise is typical of switching DC-DC Converters.

3. The exposed pad centered on the package bottom must be

connected to RF and DC ground. (For PQFN Packages)

4. During turn-on, the device requires an initial start up current (Icc)

specified as “Turn-on Current”. Once operational, Icc will drop to the

specified levels.

5. The DC-DC converter is guaranteed to start in 100 µs as long as the

power supplies have the maximum turn-on current available for start-

up.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.

Moisture Sensitivity

The MSL rating for this part is defined as Level 2

per IPC/JEDEC J-STD-020. Parts shall be stored

and/or baked as required for MSL Level 2 parts.
